@HP. see the edit. When you said you used 2 72" doors I assumed that the 3rd was smaller...

I was thinking about the 3rd track option too but then the wall area on top is not wide enough. Plus there is not enough track to run. So I guess I am not sure if I use the correct parts for this scenario.

Make the area wider with a wood plank or similar...

Is taking the doors back and getting 28" available to you? Or at least 2 being 28". This way you can have an overlap if you want, but also if you set up the 2 smaller doors on one track, larger 32" on the other, you then will have a maximum opening of 27". Another option is to make one door a swing open door on one side, the side with the wall, so that you swing that door out against the wall, the other 2 are pushed to the opposite side, this then gives you maybe 48"
